摘要
针对西部某矿区煤层气储层松软的特征,结合煤层气储层损害机理,以DF-H01水平井为研究对象,通过研究区储层特征研究,优化钻井液配方,对不同井段设计不同的钻井液配方,有效保护了储层,增加了煤层钻遇率,减少了井内事故,为该区实施煤层气水平井提供了技术借鉴。
According to the characteristics of the soft reservoir in western China,combined with the CBM reservoir damage mechanism,DF-H01 horizontal Wells as the research object,through the study the reservoir characteristics in the study area,optimized drilling fluid formulation,designed for different sections of different drilling fluid formula,effectively protect the reservoirs,increased the seam drill encounter rate,reduced accidents in the well.It provides a technical reference for implementing CBM horizontal well in this area.
